Gaps in time series.
I like the fact that in subtracting two time series objects that there is some effort to align the series. So if I have a time series of that begins at 1 and one that begins at 2 a subtraction operation makes sure that the proper values are subtracted. But I am unclear as to the best way to build a time series with "holes". say that I ha...

Regression and time series
Can someone shed some light on this obscure portion of the help for lm? "Considerable care is needed when using 'lm' with time series. Unless 'na.action = NULL', the time series attributes are stripped from the variables before the regression is done. (This is necessary as omitting 'NA's would invalidate the time series attributes, and if 'NA's are omitted in the middle of the serie...

xyplot: superpose 2 time series with different time intervals
I could use some advice regarding xyplot. I've got 2 time series. Both cover approximately the same period of time (ie, 1940 to 2009). But one series has annual data and the other has monthly data. One refers to university enrollment; the other to unemployment rates. Both are currently in the same data frame. I'd like to use the monthly times series as a...

a high-level command for drawing a multiple series graph with each series having a label
I wish to draw a graph representing multiple series (sets of x,y points). Each series has its own label and points within each series are joined by a line ordered by their X cooridnate. I would also like a legend automatically showing which each series is. Which high-level command can serve this purpose? I looked at my book but can't find...

irregular time series
Background: OS: Linux Mandrake 9.1 release: R 1.9.0 editor: Xemacs 21.4 frontend: ESS 5.1.23 --------------------------------- Colleagues I have two time series (upwelling index and water temperature) of evenly spaced, daily data over 18 months, but the upwelling index series has a gap of about 2 months right in the middle of it. I want to do the acf, pacf, ccf, and a cross-spectral analysis of the two series. I realise that I could just break each ser...

Whitening Time Series
Hi R users, I am doing cross correlation analysis on 2 time series (call them y-series and x-series) where I need the use the model developed on the x-series to prewhiten the yseries.. Can someone point me to a function/filter in R that would allow me to do that? Thanks in advance for any help! -- View this message in context: http://www.nabble.com/Whitening...

Time series (ts) questions.
I have been working with the base time series object (ts) and I had a couple of questions that hopefully this group can help me with: 1) What is the best why to append an observation to an existing time-series? Suppose I have a time series: t <- ts(1:12, frequency=5) This would generate two complete cycles and one remainder. Now I woul...

multiple comparisons of time series data
I am interested in a statistical comparison of multiple (5) time series' generated from modeling software (Hydrologic Simulation Program Fortran). The model output simulates daily bacteria concentration in a stream. The multiple time series' are a result of varying our representation of the stream within the model. Our main question is: Do the different...
